KSB Introduces New Waste Water Pump with Efficient Hydraulic System

May 2020

The KSB Group has introduced new submersible motor pump to its Amarex type series. This new addition is suitable for applications including waste water, sludge treatment and the transport of storm water. The pump can handle waste water containing long fibres, solid substances, fluids containing gas and sludge, service water and grey water. Equipped with either free-flow impellers (F-max) or open two-vane impellers (D-max) the new Amarex NG will go on show at IFAT 2020 in May.

Users can choose the appropriate impeller type to suit their requirements, such as low waste water flow rates at high heads and high flow rates at lower heads. Pump variants featuring D-max impellers are available with a D-flector, which significantly increases resistance to clogging. A multitude of material and mechanical seal variants ensures that the user can transport a wide range of corrosive and abrasive fluids.

The impellers’ non-clogging feature markedly reduces maintenance requirements compared with conventional designs. Significantly the Amarex NG offers high levels of hydraulic efficiency combined with high-efficiency IE3 motors creating low energy consumption during operation. The Amarex NG series has a maximum head of 42m and a maximum flow rate of 320 m3/h. When designing the pump, engineers attached great importance to the pumps achieving a long service life. This is ensured by a generously dimensioned motor, robust rolling element bearings and a corrosion-resistant stainless steel shaft.

An environmentally friendly, non-toxic oil fill provides continuous lubrication of the mechanical seal. As is common practice with this type of pump, installation in the pump sump is made via a ‘duckfoot’ bend. A large range of adapter claws allows the use of duckfoot bends from other manufacturers, so it is possible to make changes without involving a major installation effort. Sealing between duckfoot bend and the pump discharge flange is by a newly developed water-tight and durable U-profile ring. Users also have several options when choosing the arrangement for placing the pump on the duckfoot bend: They can opt for guide hoop, guide wire, single guide rail or twin guide rail arrangement.

The pumps are designed for easy repair and maintenance, and at the end of the pump’s life cycle, most of components can be dismantled and recycled.
